Description

[0001] The invention relates to a device for mounting at least one vehicle component group comprising at least two vehicle components onto a vehicle body structure.

[0002] Devices for mounting at least one vehicle component group comprising at least two vehicle components onto a vehicle body shell are known in principle from the prior art. Such devices can also be referred to as mobile component carriers, whereby assemblies such as a powertrain, a body, and / or a chassis component are supported by the device and held in a defined relative position to each other in order to facilitate their assembly. A disadvantage of this is that if a different vehicle type or the components or assemblies to be mounted are changed, a different or modified device for supporting the components or assemblies is required.

[0003] DE 10 2016 005 648 A1 describes a device for aligning a front-end module on a motor vehicle, wherein the device can be placed on a motor vehicle body in a defined position. The device comprises a frame made of interconnected profiles.

[0004] From the catalog “Witte Barskamp KG: Catalogues / Modular clamping systems / ALUFIX / ALUFIX-2019-DWeb1. 21354, Bleckede, Germany, 04 / 2019. 1, 6-9, 65, 108-114, 218” a grid-like structure is known which consists of elongated elements with a uniform and symmetrical hole pattern, wherein a connection of these elements is effected by means of connectors engaging in holes of the hole pattern.

[0005] A grid-like structure of similarly designed elongated profiles is also known from the company publication "TÜNKERS Maschinenbau GmbH: One Screw System (TOS) & Euro-GreiferTooling System (EGT). 40880 Ratingen, Germany, 04 / 2017. 3-18 to 3-21, 3-24 to 3-30." These profiles also have a uniform hole pattern, by means of which connecting elements are screwed on to join several elongated profiles.

[0006] The invention is based on the objective of providing a device which, in particular with regard to a simple, quick and cost-effective measure, enables the assembly of different vehicle component groups, in particular vehicle assemblies, and a vehicle body structure, in particular a vehicle body or a chassis.

[0007] The problem is solved by a device for mounting at least one vehicle component group comprising at least two vehicle components onto a vehicle body shell according to claim 1. The dependent claims relate to possible embodiments of the device.

[0008] The invention relates to a device for mounting at least one vehicle component group comprising at least two vehicle components onto a vehicle body structure, in particular onto a body and / or a chassis, wherein the device comprises: at least one longitudinal body and at least one transverse body, which are connected to one another and together form a base support for directly or indirectly supporting or holding the vehicle components to be mounted. The device is characterized in that at least one transverse body can be selectively attached to the at least one longitudinal body in a first position and / or orientation and in a second position and / or orientation that differs from the first, particularly with regard to a specific mounting situation of the vehicle components to be mounted.Typically, the device is used as a carrier for at least temporarily holding a component group consisting of at least two parts and / or a vehicle body shell in order to connect the other components. A vehicle body shell can be understood to be, in particular, a body or at least a body component and / or a chassis or at least a chassis component and / or a powertrain or a powertrain component. Because the components can be held, and in particular fixed, on the device, especially in a defined orientation and / or position relative to each other, the components held or fixed, or movably mounted or guided on the device within limited limits, can be connected to each other in a simple, precise, and convenient manner.

[0009] The actual joining of the components can be carried out by manual intervention of a production worker and / or by intervention of computer-controlled manipulators (e.g. robots).

[0010] Depending on the vehicle being assembled, the vehicle component groups being joined, and / or the vehicle's body shell, mounting points or attachment locations for fasteners may vary. To ensure accessibility to these mounting points and / or attachment locations for inserting fasteners and / or using tools to secure them, the fixture must provide appropriately sized recesses or clearances.By being able to selectively attach at least one transverse body to the at least one longitudinal body in a first position and / or orientation and in a second position and orientation that differs from the first, particularly with regard to a specific assembly situation of the vehicle components to be mounted, it is achieved that the position and / or orientation of the at least one transverse beam relative to the at least one longitudinal beam can be changed and thus adapted to the vehicle component groups to be supported by the base body or by the device.

[0011] This allows the device to be adapted to different vehicle types or depending on the installation situation of the respective vehicle component groups and a vehicle body structure.

[0012] A vehicle component group can, for example, comprise an assembly of a vehicle to be assembled, such as a machine set consisting of several interacting individual machines, devices, or equipment. The vehicle body shell can be any type of vehicle component, particularly a higher-level one. Specifically, the vehicle body shell is a body and / or a chassis and / or a powertrain of a vehicle to which vehicle component groups are to be attached. The body shell can, for example, comprise a non-unibody or a unibody construction and thus form a basic vehicle frame in addition to the superstructure. A chassis (also referred to as a frame or chassis) forms a basic framework that supports the drive system, the body shell, and the payload, and stabilizes it against external forces.

[0013] It may be provided that the transverse and longitudinal bodies are formed at least partially from similar or identical components, in particular raw components or semi-finished products. For example, at least one identical extruded profile is used as a semi-finished product for both the transverse and longitudinal bodies, which is cut to different lengths for the longitudinal and transverse bodies.

[0014] The ability to change the position and / or orientation of the crossbeam and longitudinal beam relative to each other can be achieved, for example, by making the crossbeam at least temporarily displaceable relative to the longitudinal beam. In this way, the crossbeam can be moved along a path of movement, particularly one that is guided at least in sections, and locked in place once the target position is reached. Alternatively or additionally, the device can include a drive unit (e.g., a servo motor) by means of which at least one crossbeam can be moved in the longitudinal direction of a longitudinal body relative to the longitudinal beam. Furthermore, different crossbeams to be mounted or fixed to the longitudinal beam can be designed to be movable independently of one another, either manually and / or by means of a drive. In the case of a computer-aided or...By means of a drive mechanism, the relative movement of longitudinal and transverse bodies can be adapted to a cycle-based production process, particularly in series production or vehicle assembly. This allows for the joining and connecting of vehicle component groups with a vehicle body shell during series assembly, while simultaneously modifying or adjusting vehicle-specific clearances for the supply of fasteners and / or tools.

[0015] In a further embodiment, the base support may comprise at least two longitudinal bodies, in particular aligned parallel to each other and extending in the longitudinal direction, wherein the at least two longitudinal bodies can be connected to each other by at least one, in particular by several, transverse bodies. In other words, the longitudinal and transverse bodies, in particular the base support formed by them, can form a ladder-like and / or ladder-shaped structure. It may be provided that at least one transverse body, preferably at least two transverse bodies, and particularly preferably all transverse bodies of the base support, can each be attached or locked in at least two different positions and / or orientations. At least two, and in particular all, transverse bodies can also engage in a common guide and / or fastening structure of the longitudinal bodies.For example, the guide and / or fastening structure is designed as a longitudinal groove into which at least two transverse bodies with protrusions corresponding to the longitudinal groove can be movably mounted and / or fixed in position.

[0016] It is possible that at least one longitudinal body and at least one transverse body of the base support are arranged lying in a common plane. In particular, the longitudinal and transverse bodies of the base support form a grid-like or lattice-like, preferably a ladder-like or -shaped, basic support structure. Preferably, all longitudinal and transverse bodies of the base support are arranged or formed in a common plane. In the intended use of the device, the common plane is aligned parallel to a mounting surface or to a factory floor. The grid-like or ladder-like structure enables the creation of a rigid and stable structure for the basic support structure. Furthermore, by aligning the longitudinal and transverse bodies at right angles to each other, movement of the longitudinal and transverse bodies relative to each other can be easily facilitated.

[0017] In a further advantageous embodiment, a first longitudinal end of a first longitudinal body and a second longitudinal end of a second longitudinal body can be connected to each other via a longitudinal end body. Preferably, the longitudinal end body extends over a first outer side surface of the first longitudinal body and / or over a second outer side surface of the second longitudinal body. The longitudinal end body can, for example, run parallel to the transverse bodies. The longitudinal end body can also be flush with a longitudinal end of the longitudinal body, or be placed on the longitudinal end of the longitudinal body, or be arranged directly adjacent to or in contact with it. The longitudinal end body can also be, for example, detachably connected to the longitudinal body.

[0018] Alternatively or additionally, it can be provided that at least one transverse end body, in particular one extending parallel to a longitudinal body, is arranged or formed on at least one outside a central area of ​​the device formed by at least two longitudinal bodies. Preferably, the transverse end body is connected to at least one longitudinal body via an outer transverse element and / or via a longitudinal end body. The transverse end body can, for example, extend parallel to the longitudinal body. The transverse end body can also optionally be detachably connected to an outer transverse element that is connected to the longitudinal body and / or to a longitudinal end body.

[0019] The transverse end bodies can be oriented at right angles to the longitudinal end bodies. The transverse and longitudinal end bodies can also form an outer, particularly rectangular, frame of the device, especially the base support. In other words, the transverse and longitudinal end bodies can at least partially surround or enclose the transverse and longitudinal bodies on the outside.

[0020] The same and / or identical semi-finished products or raw materials can be used to form the transverse and / or longitudinal end bodies as for the transverse and / or longitudinal bodies. This increases the use of identical parts, at least for the initial manufacturing steps.

[0021] It is possible that at least one auxiliary body, and in particular several auxiliary bodies, for supporting at least one vehicle component group comprising at least two vehicle components is detachably attached to the base support, particularly on a surface of the base support facing away from the installation surface of the device or a factory floor. The auxiliary bodies can represent holding and / or supporting elements that can be attached to the base support, at least temporarily. Because the base support comprises at least one, and in particular several, auxiliary bodies, a device, and in particular a base support, can be modified more quickly and / or with less effort by adding and / or removing and / or replacing an auxiliary body.

[0022] The auxiliary body can, for example, have at least one auxiliary transverse body that can be detachably connected or joined to an auxiliary longitudinal body, wherein at least one auxiliary transverse body can be selectively attached in a first position and / or orientation relative to an auxiliary longitudinal body and in a second position and / or orientation different from the first position and / or orientation. The auxiliary transverse bodies and auxiliary longitudinal bodies can form a grid-like or lattice-like and / or a ladder-like or ladder-like structure of the auxiliary body and / or, in particular, can be arranged exclusively in a common plane.Preferably, with regard to a specific assembly situation of the vehicle components to be assembled, an auxiliary transverse body can be detachably attached to at least one auxiliary longitudinal body in a first position and / or orientation relative to an auxiliary longitudinal body and in a second position and / or orientation different from the first position and / or orientation. Thus, depending on the required clearance, e.g., for inserting a tool onto a component of a vehicle component group and / or a vehicle body shell, the shape and / or extent of the clearance can be changed or adapted by changing the position and / or orientation of at least one auxiliary transverse body relative to an auxiliary longitudinal body.

[0023] Furthermore, it may be provided, for example, that the at least one auxiliary longitudinal body and / or one auxiliary transverse body is designed at least partially similarly or identically to a longitudinal body and / or transverse body, and / or that an interface for connecting the auxiliary longitudinal body to the auxiliary transverse body is designed at least partially similarly or identically to an interface for connecting the longitudinal body to the transverse body. An economically advantageous variant is achieved by using identical parts for at least the raw components (e.g., semi-finished products) of the longitudinal bodies, transverse bodies, auxiliary longitudinal bodies, and / or auxiliary transverse bodies. For example, an identical extruded profile is used as the basic component or raw component for the longitudinal body, the transverse body, the auxiliary longitudinal body, and the auxiliary transverse body. These extruded profile sections can then undergo different processing (e.g.,(cutting to length), in order to develop the properties specific to the longitudinal body, transverse body, auxiliary longitudinal body and / or auxiliary transverse body.

[0024] The interface between longitudinal bodies, transverse bodies, auxiliary longitudinal bodies, and / or auxiliary transverse bodies can, for example, include similar and / or identical mounting elements and / or counter-mounting elements and / or, if applicable, intermediate mounting elements. Alternatively or additionally, the type and / or method of locking via the interfaces or via the mounting elements and counter-mounting elements can be similar or identical for the longitudinal and transverse bodies and the auxiliary longitudinal and auxiliary transverse bodies. For example, locking can be achieved by means of a clamping mechanism provided at the interface, which can include a handle for manual operation and an eccentric. Alternatively or additionally, a motor-driven relative movement between the longitudinal body and the transverse body, and between the auxiliary longitudinal body and the auxiliary transverse body, can be achieved.

[0025] Typically, the auxiliary bodies are shorter in length and / or width than the base support. They can also be used as a pallet-like attachment on a base support. In this case, the auxiliary body can be designed like a floating pallet, meaning that it can move, at least within predefined limits, in at least one spatial direction lying in its principal extension plane. This can be achieved, for example, by using ball bearings to support the auxiliary body. These ball bearings are movably mounted in concave or similar ball receptacles that define the limited range of motion.

[0026] According to the invention, at least one longitudinal body and / or an auxiliary longitudinal body comprises a mounting element, and at least one transverse body and / or an auxiliary transverse body comprises a counter-mounting element. The mounting element and the counter-mounting element are configured such that, in the final assembly state, they form a releasable force-fit and / or form-fit connection between the longitudinal and transverse bodies and / or between the auxiliary longitudinal and auxiliary transverse bodies. The connection between the mounting element and the counter-mounting element can include a screw connection, wherein at least the mounting element and / or the counter-mounting element has at least one through-hole for passing a screw shank through it. The mounting element and / or the counter-mounting element can include a recessed section provided with an internal thread.

[0027] The fixing element used for the connection can, for example, include engaging a recess provided in the fastening partner. The fastening partner can have a plurality of recesses into which the fixing element can selectively engage, depending on the position and / or orientation of the longitudinal body relative to the transverse body and / or of the auxiliary longitudinal body relative to the auxiliary transverse body in which the fixing or locking is to occur. It can be advantageous if the mounting element and / or the counter-mounting element has a plurality of recesses arranged or formed in a grid pattern, in particular as a hole grid or recess grid. The grid pattern allows, in particular, a plurality of different predefined positions and / or orientations of the longitudinal body relative to the transverse body or of the auxiliary longitudinal body relative to the auxiliary transverse body.

[0028] The fastening device itself can comprise at least one screw connection, one bolt connection, e.g., a locking bolt, and / or a clamping mechanism, preferably by means of an eccentric. Finally, the fastening device can also be represented by a controllable motor, which, in the event of the transverse body being locked relative to the longitudinal body, can be restricted in its rotation in order to consequently inhibit or block the change in position and / or orientation that it can perform.

[0029] The fastening mechanism can be operated manually and / or computer- or robot-assisted. For example, a production worker guides a screwdriver to the corresponding screw heads of the fasteners. Alternatively, the fastener can be secured using a screwdriver attached to a robot manipulator.

[0030] For example, the longitudinal body-side and / or auxiliary longitudinal body-side mounting element may have a recess, in particular a straight groove, and the transverse body-side and / or auxiliary transverse body-side mounting counter-element may have an engagement protrusion that corresponds at least partially to the recess. For example, a substantially rectangular protrusion engages in the corresponding section of a straight longitudinal groove for the desired orientation and / or positioning. Preferably, a clamping or other fixing is provided in the area of ​​engagement. Here, the recess, designed as a straight longitudinal groove, may run at least partially, and in particular completely, parallel to a longitudinal axis of the longitudinal body and / or the auxiliary longitudinal body.

[0031] It is possible that, in the final assembly state, at least one intermediate assembly element can be arranged or is arranged between the assembly element and the counter-assembly element. In particular, the at least one intermediate assembly element is designed such that, in the final assembly state, it fills at least a portion, and especially predominantly or completely, of the free space between the assembly element and the counter-assembly element. The intermediate assembly element facilitates the simplified release or removal of the connection between the assembly element and the counter-assembly element. Removing the intermediate assembly element creates a free space in the area of ​​the assembly element and the counter-assembly element. This free space allows for the relative movement of the assembly element and the counter-assembly element, or of the longitudinal body to the transverse body, etc.Moving between auxiliary longitudinal and auxiliary transverse bodies is easier because the risk of jamming can be reduced by the available clearance. This play created by the clearance facilitates the movement of longitudinal and transverse bodies, or of auxiliary longitudinal and auxiliary transverse bodies.

[0032] The intermediate mounting element can, for example, have a handle as an engagement point for manual or tool-assisted movement. For this purpose, the intermediate mounting element can, for example, have an eyelet or a recess that can serve as an engagement surface for the use of a tool.

[0033] In a further advantageous embodiment, a transverse body is mounted between two longitudinal bodies, with a connection to the longitudinal body at both ends of the transverse body via an interface comprising a mounting element and a counter-mounting element. It may be provided that an intermediate mounting element is arranged, or can be arranged, only on one of the two sides, i.e., exclusively on one side, of the transverse body. This is because it is sufficient to create a gap only on one side of the transverse body relative to the respective longitudinal bodies to facilitate the movement of the transverse body relative to the two longitudinal bodies. In this case, the side to be fitted with an intermediate mounting element can be marked with a marking on the transverse body side to indicate the mounting location of the intermediate mounting element to the production worker. The intermediate mounting element can also be used as a spacer element or...It may be designed as a spacer plate. The intermediate mounting element may also be multi-part, meaning that there is a free space with several sections between the transverse body and the longitudinal body, or between the auxiliary longitudinal body and the auxiliary transverse body, which can be filled and / or filled by several intermediate mounting elements or spacer elements.

[0034] According to the invention, the mounting element and / or the counter-mounting element is designed as a machined component, specifically as a component machined by a subtractive process, and can be connected or joined to the longitudinal body and / or auxiliary longitudinal body and / or transverse body by a material-bonded connection, in particular by a welded joint. It is provided according to the invention that, in a first step, the component (e.g., of metal plates or metal strips) is applied to a base body (e.g., a semi-finished product) of the longitudinal body and / or transverse body and / or auxiliary longitudinal body and / or auxiliary transverse body during a material-bonded joining process (e.g., welding), and subsequently, machine-assisted or subtractive machining, in particular milling, of the component is carried out to form at least the target geometry of the mounting element and / or the counter-mounting element in sections.The semi-finished product used to form longitudinal and / or transverse bodies and / or auxiliary longitudinal and / or auxiliary transverse bodies can, for example, comprise a hollow steel structural section or an extruded profile. Because machining takes place only in a second step, any distortion resulting from the welding process cannot adversely affect the geometry formed by the subsequent machining. The downstream machining can generally include, at least in some sections, fine machining, particularly subtractive machining. The downstream machining, or machining performed after the creation of the metallurgical bond, can also include drilling and / or honing.

[0035] In a further advantageous embodiment, the mounting element and / or the counter-element can have a first group of fixing element receiving recesses and a second group of fixing element receiving recesses that differ from the first group, wherein the fixing element receiving recesses of the two groups differ in their shape and / or type, in particular in their diameter and / or thread type and / or thread form and / or tolerance. Furthermore, it can be provided that the first and / or the second group of fixing element receiving recesses is / are arranged or formed along a straight axis parallel to the longitudinal axis of the longitudinal body and / or the transverse body and / or the auxiliary longitudinal body and / or the auxiliary transverse body.

[0036] For example, a first group of fixing element receptacles is designed as threaded holes and / or threaded blind holes. A second group of fixing element receptacles can be arranged or designed in the same plane or in a plane parallel to the first group and, in particular, may include a thread form and / or type different from the first group. The fixing element receptacles of the second group can also be designed as simple through-holes without a thread. For example, the fixing element receptacles of the second group are designed as locating bores or locating recesses for receiving corresponding dowel pins. The fixing element receptacles of the first and / or second group can be arranged or designed on the mounting element and / or on the counter-mounting element at a grid spacing.

[0037] The longitudinal-side mounting element and / or the transverse-side mounting counter-element can, for example, at least partially accommodate a component holder and / or a component lifter and / or a connecting device and / or other aids helpful for assembling the vehicle component group and / or the vehicle body shell. This allows the mounting elements and / or mounting counter-elements to fulfill a dual function: on the one hand, they can be used to fasten longitudinal and transverse bodies or auxiliary longitudinal and auxiliary transverse bodies, and on the other hand, they can be used to fasten aids supporting the assembly process. This means that the interface for fixing longitudinal and transverse bodies or auxiliary longitudinal and auxiliary transverse bodies can be used, at its interface sections not used during initial configuration, for attaching assembly aids.A connecting device can be used to connect or support the device against a supporting surface or factory floor and / or against a mobile transport vehicle (e.g., an automated guided vehicle, also known as an AGV) supporting the device.

[0038] In addition to the device for assembling vehicle components, the invention also relates to a method for assembling vehicle components, in particular for assembling at least one vehicle component group comprising at least two vehicle components onto a vehicle body structure using a device according to one of the preceding claims, wherein in a first assembly situation a transverse body is detachably attached to the at least one longitudinal body in a first position and / or orientation and in a second assembly situation in a second position and / or orientation.

[0039] Preferably, in the case of converting the device from a first vehicle to be mounted to a second vehicle, which has different mounting locations for the fastening means than the first vehicle, the method can be carried out in a single conversion step such that a change in the position and / or orientation of at least one transverse body relative to a longitudinal body is performed. It can be provided that a fastening at one, and in particular at all, interfaces of a transverse body and a longitudinal body is loosened. Then, a movement of the transverse body relative to a longitudinal body can be performed, in particular a guided movement at least in sections. Subsequently, the transverse body can be fixed or fastened to the longitudinal body.These process steps enable the provision of a device as a mobile component carrier, which can be adapted or modified in a simple, convenient and cost-effective manner to the conditions of a changing assembly situation (change from a first to a second vehicle configuration).

[0040] Alternatively or additionally, it may be provided that within at least one auxiliary body, at least one auxiliary transverse body is adjustable in position and / or orientation relative to an auxiliary longitudinal body, or can be fixed in at least two different positions and / or orientations. This adjustability of the auxiliary body's geometric shape allows it to be adapted to the conditions or assembly requirements of the vehicle being assembled. The geometric shape includes, in particular, the spaces formed by the gaps between the auxiliary transverse bodies and / or auxiliary longitudinal bodies for the passage of tools and / or assembly materials.

[0041] Furthermore, when changing the vehicle being assembled, it is possible to exchange or replace at least one auxiliary body on the device with one adapted to the vehicle being assembled. For example, the device can comprise three auxiliary bodies for a first vehicle, whereby when switching to assembling a second vehicle different from the first, at least one auxiliary body can be exchanged for another. This enables quick and cost-effective reconfiguration of the device when changing the vehicle being assembled, with the areas of the device requiring modification preferably being adapted to the vehicle being assembled by exchanging individual auxiliary bodies. The exchange of the at least one auxiliary body can be carried out, for example, manually by a production worker and / or robotically.Particularly in the case of at least a semi-automated, and especially a fully automated, replacement of the auxiliary body, a quick and reliable adjustment of the device can be carried out, possibly within one assembly cycle.

[0042] An adaptation or modification of at least one auxiliary body of a device may include (a) its relative movement to a base body and / or (b) its change in the orientation and / or position of at least one auxiliary longitudinal body to an auxiliary transverse body and / or (c) its replacement with another auxiliary body.

[0043] All advantages, details, designs and / or features of the device according to the invention are transferable or applicable to the method according to the invention.

[0044] The invention is explained in more detail with reference to exemplary embodiments in the drawings. These show: Fig. 1 a perspective schematic representation of a device in a top view according to an exemplary embodiment; Fig. 2 a perspective schematic representation of a device according to Fig. 2 from the bottom; Fig. 3 a perspective schematic representation of a device in a top view according to a further embodiment; Fig. 4 a schematic representation of a device equipped with a vehicle component group according to an exemplary embodiment; Fig. 5 a schematic cross-sectional representation of a longitudinal body and a transverse end body and a transverse element connecting them according to an exemplary embodiment; Fig. 6 a schematic detailed representation of a cross-section of a transverse end body according to detail A from Fig. 5; Fig. 7 a perspective schematic representation of a transverse body interface according to an exemplary embodiment.

[0045] The device 1 shown in the figures serves for mounting at least one vehicle component group 2, 2' comprising at least two vehicle components onto a vehicle body structure 3, in particular onto a body and / or a chassis. The device 1 has at least one longitudinal body 4, 4' and at least one transverse body 5, 5', wherein the longitudinal and transverse bodies 4, 4', 5, 5' are connected to each other and together form a base support 6 for carrying the vehicle components or the vehicle component group 2, 2' to be mounted. It is provided that at least one transverse body 5, 5' can be selectively attached to the at least one longitudinal body 4, 4' in a first position and / or orientation and in a second position and / or orientation that differs from the first, particularly with regard to a specific mounting situation of the vehicle components or the vehicle component group 2, 2'.

[0046] The base support 6 has at least two longitudinal bodies 4, 4', in particular aligned parallel to each other and extending in the longitudinal direction, wherein the at least two longitudinal bodies 4, 4' can be connected to each other or are connected to each other by at least one, in particular by several, transverse bodies 5, 5'. According to Fig. Figure 2 shows that the longitudinal bodies 4, 4' are connected via two transverse bodies 5, 5'. A further connection of the longitudinal bodies 4, 4' can be made via longitudinal end bodies 7, 7'.

[0047] The base support 6 can have a lattice-like or -shaped and / or a ladder-like or -shaped structure formed by the longitudinal bodies 4, 4' and transverse bodies 5, 5'. Such a ladder-like structure is particularly evident from the Fig. 2. This structure can ensure the essential stability and / or stiffness, in particular torsional stiffness, of the base beam 6. Alternatively or additionally, a longitudinal end body 7, 7' or a transverse end body 8, 8', 8" can contribute to the stability and / or stiffness of the structure of the base beam 6. At least one longitudinal body 4, 4' and at least one transverse body 5, 5' of the base beam 6 can be arranged or formed lying in a common plane, which can be the main extension plane of the base beam 6, in which the longitudinal end bodies 7, 7' and / or transverse end bodies 8, 8', 8" can optionally also run internally, in particular exclusively in the main extension plane of the base beam 6.The arrangement, in particular the exclusive arrangement, within the main extension plane can be at least sectionally or completely for the respective longitudinal bodies 4, 4' and / or transverse bodies 5, 5', 5" and / or longitudinal end bodies 7, 7' and / or transverse end bodies 8, 8', 8" and / or outer transverse element 12, 12', 12".

[0048] A first longitudinal end 9 of a first longitudinal body 4 and a second longitudinal end 9' of a second longitudinal body 4' can be connected to or joined to each other via a longitudinal end body 7, 7'. Preferably, the longitudinal end body 7, 7' extends over a first outer side surface 10 of the first longitudinal body 4 and / or over a second outer side surface 10' of the second longitudinal body 4', cf. Fig. 1 or Fig. 2. In the Fig. In the alternative embodiment shown in Figure 3, the structure of the base support 6 has a ladder- or grid-like structure, wherein this structure does without transverse end bodies 8, 8', 8" and without longitudinal end bodies 7, 7' extending beyond the outer side surfaces 10, 10'.

[0049] At least one transverse end body 8, 8', 8" can be arranged or formed on at least one transverse end body 8, 8', 8" which runs parallel to a longitudinal body 4, 4' and is located outside a central area 11 or center of the device 1 formed by at least two longitudinal bodies 4, 4'. The transverse end bodies 8, 8', 8" can furthermore preferably be connected to at least one longitudinal body 4, 4' via an outer transverse element 12, 12', 12" and / or via a longitudinal end body 7, 7'. The outer transverse elements 12, 12', 12" are arranged outside the central area 11 defined by the longitudinal bodies 4, 4' or are arranged on the side surfaces 10, 10' of the longitudinal bodies 4, 4' facing away from the central area 11 or extend outwards from it.

[0050] The device 1 further comprises at least one auxiliary body 13, 13', 13", in particular several auxiliary bodies 13, 13', 13", on the base support 6 for supporting at least one or at least two vehicle components or for supporting vehicle component groups 2, 2', wherein the at least one auxiliary body 13, 13', 13" is detachably attachable to the base support 6, in particular to the longitudinal body 4, 4', or is attached thereto. The at least one auxiliary body 13, 13', 13" is positioned on a surface 15, 15' of the base support 6 or of the longitudinal body 4, 4' facing away from a mounting surface 14 of the device 1. The auxiliary bodies 13, 13', 13" can have a planar or flat structure and, within a plane of movement running parallel to the main extension plane of the base support 6, can be at least temporarily movable or at least temporarily lockable in their movement, or can be mounted on the base support 6 in a lockable manner.

[0051] The auxiliary body 13, 13', 13" can have at least one auxiliary transverse body 17, 17', 17" which can be connected or joined to an auxiliary longitudinal body 16, 16', in particular detachably, wherein at least one auxiliary transverse body 17, 17', 17" can be optionally attached to the at least one auxiliary longitudinal body 16, 16' in a first position and / or orientation and in a second position and / or orientation that differs from the first, particularly with regard to a specific assembly situation of the vehicle components or vehicle component group 2, 2' to be assembled. For example, the auxiliary longitudinal bodies 16, 16' and the auxiliary transverse bodies 17, 17', 17" can be arranged or designed such that the auxiliary body 13, 13', 13" has a ladder-like and / or grid-like or ladder-shaped and / or grid-shaped structure. exhibits.

[0052] The at least one auxiliary longitudinal body 16, 16' and / or auxiliary transverse body 17, 17', 17" can be designed, at least in sections, in the same or identical manner as a longitudinal body 4, 4' and / or transverse body 5, 5'. Alternatively or additionally, an interface for connecting the auxiliary longitudinal body 16, 16' with the auxiliary transverse body 17, 17', 17" can be designed, at least in sections, in the same or identical manner as an interface for connecting the longitudinal body 4, 4' with the transverse body 5, 5'. Due to the similarity or at least sectionally identical design of longitudinal bodies 4, 4', transverse bodies 5, 5', auxiliary longitudinal bodies 16, 16' and auxiliary transverse bodies 17, 17', 17", the use of identical parts and / or at least the use of identical or identical semi-finished products for the manufacture of the longitudinal bodies 4, 4', transverse bodies 5, 5', auxiliary longitudinal bodies 16, 16' and auxiliary transverse bodies 17, 17', 17" can be used.

[0053] For example, at least one longitudinal body 4, 4' and / or an auxiliary longitudinal body 16, 16' can comprise a mounting element 18, 18', 18" and at least one transverse body 5, 5' and / or an auxiliary transverse body 17, 17', 17" can comprise a counter-mounting element 19, 19', wherein the mounting element 18, 18', 18" and the counter-mounting element 19, 19' are designed such that, in the final assembly state, the mounting element 18, 18', 18" and the counter-mounting element 19, 19' form a releasable force-fit and / or form-fit connection between longitudinal and transverse bodies 4, 4', 5, 5' and / or between auxiliary longitudinal and auxiliary transverse bodies 16, 16', 16", 17, 17'. Alternatively or additionally, corresponding mounting elements 18, 18', 18" and mounting counter elements 19, 19' are used for fastening longitudinal end bodies 7, 7', transverse end bodies 8, 8', 8" and / or transverse elements 12, 12', 12".

[0054] The longitudinal body-side and / or auxiliary longitudinal body-side mounting element 18, 18', 18" can have a recess 20, in particular a straight groove, and the transverse body-side and / or auxiliary transverse body-side counter-mounting element 19, 19', 19" can have an engagement protrusion 21 that corresponds at least partially to the recess 20. The positive locking created by the recess 20 and the engagement relief 21, or the interlocking action itself, allows the transverse body 5, 5' to be supported by the longitudinal body 4, 4', and the auxiliary transverse body 17, 17', 17" to be supported by the auxiliary longitudinal body 16, 16', thus ensuring at least a hold in the z-direction or a hold in the vertical direction. The actual fixing of the movement of the longitudinal body 4, 4' relative to the transverse body 5, 5', or of the auxiliary longitudinal body 16, 16' relative to the auxiliary transverse body 17, 17', 17", can be achieved by further means (e.g., fasteners).

[0055] In the final assembly state shown in the figures, at least one intermediate assembly element 22, 22' can be arranged or is arranged between the assembly element 18, 18', 18" and the counter-assembly element 19, 19', in particular the at least one intermediate assembly element 22, 22' is designed such that in the final assembly state it fills at least a free space 23, 23' between the assembly element 18, 18', 18" and the counter-assembly element 19, 19' at least partially, in particular predominantly or completely, cf. Fig. 6. The intermediate mounting element 22, 22' can be easily detached and removed. The resulting clearance 23, 23' facilitates the movement of the mounting element 18, 18', 18" relative to the counter-mounting element 19, 19', and also facilitates the relative movement of longitudinal and transverse bodies 4, 4', 5, 5' or auxiliary longitudinal bodies 16, 16' and auxiliary transverse bodies 17, 17', 17" because the components have play to allow movement and the risk of jamming is reduced.

[0056] The intermediate mounting element 22, 22' can, for easier handling, have, for example, a handle 24 as an engagement point for manual or tool-assisted movement of the intermediate mounting element 22, 22'. This handle 24 can, for example, be designed as an eyelet, cf. Fig. 7. In the illustrated embodiment, the handle 24 is shown as an elongated hole formed in the final assembly state on an outer edge of the interface of the transverse body 5, 5' or the assembly counter element 19, 19'.

[0057] Furthermore, a marking 25 can be arranged or formed in the area of ​​the free space 23, 23' on the transverse body side and / or longitudinal body side and / or auxiliary longitudinal body side and / or auxiliary transverse body side, which indicates on which side of the transverse body 5, 5' and / or the auxiliary transverse body 17, 17', 17" the intermediate mounting element 22, 22' is to be arranged. Alternatively, the marking 25 can also be arranged on the longitudinal body 4, 4' and / or on the auxiliary longitudinal beam 16, 16'. It can be provided that an intermediate mounting element 22, 22' is to be arranged on only one of the two end faces or face faces of the transverse body 5, 5' and / or the auxiliary transverse body 17, 17', 17". The indication or marking 25 prevents incorrect assembly of the intermediate mounting element 22, 22', which is designed in particular as a spacer plate.

[0058] The intermediate mounting element 22, 22' further comprises, in particular, blind-hole-like or blind-hole-shaped recesses 26, 26', which are designed such that, despite the engagement of a bolt (not shown) or a screw shank (not shown) between a transverse body 5, 5' and a longitudinal body 4, 4' or between an auxiliary transverse body 17, 17', 17" and an auxiliary longitudinal body 16, 16', the intermediate mounting element 22, 22' can be removed through the area of ​​the recesses 26, 26' which is open on one side. In other words, any shank portions of a screw and / or a bolt or other fasteners that penetrate a main extension plane of the intermediate mounting element 22, 22' are not trapped within the intermediate mounting element 22, 22', so that the intermediate mounting element 22, 22' can be removed.

[0059] The blind-hole-like and / or blind-hole-shaped recesses 26, 26' can also have sliding and / or guide ramps 27, 27'. This facilitates the insertion or centering of an intermediate mounting element 22, 22' into the intended area of ​​the clearance 23, 23', even if screw shank and / or bolt shank sections already penetrate the main extension plane of the intermediate mounting element 22, 22'.

[0060] The mounting element 18, 18', 18" and / or the counter-mounting element 19, 19' can be designed as a machined component, in particular as a component machined by a chip-removing process, and can be connected or joined to the longitudinal body 4, 4' and / or auxiliary longitudinal body 16, 16' and / or transverse body 5, 5' and / or auxiliary transverse body 17, 17', 17" by a force-fit and / or material-fit and / or form-fit connection, in particular by a welded connection, cf. Fig. 7. The mounting element 18, 18', 18" can be designed as a strip-like and / or plate-like body 28, which has two planes. In an inwardly offset, centrally located plane that runs parallel to the longitudinal axis of the longitudinal body 4, 4' and / or auxiliary longitudinal body 16, 16' and / or transverse body 5, 5' and / or auxiliary transverse body 17, 17', 17"

[0061] The mounting element 18, 18', 18" designed as a plate-shaped and / or plate-like body 28 can also be arranged on at least one longitudinal end body 7, 7', and / or transverse end body 8, 8', 8" and / or outer transverse element 12, 12', 12" and serve as an interface for connection with other bodies and / or mounting aids.

[0062] The strip-like and / or plate-like body 28 is, for example, welded in a first step onto the semi-finished product and / or extruded profile forming the longitudinal body 4, 4' and / or transverse body 5, 5', 5" and / or longitudinal end body 7, 7' and / or transverse end body 8, 8', 8" and / or outer transverse element 12, 12', 12" and / or auxiliary longitudinal body 16, 16' and / or auxiliary transverse body 17, 17', 17" and is subsequently subjected to machining, in particular cutting. Because the material bond is formed first and only then is the machining or the tolerance-sensitive geometry created, the latter cannot be negatively altered by thermal distortion during the creation of the material bond (e.g., welding process).This procedure allows for a relatively high tolerance for the axial parallelism of bores and / or stop surfaces to form the interface for connecting the longitudinal bodies 4, 4' and / or transverse bodies 5, 5', 5" and / or longitudinal end bodies 7, 7' and / or transverse end bodies 8, 8', 8" and / or outer transverse element 12, 12', 12" and / or auxiliary longitudinal body 16, 16' and / or auxiliary transverse body 17, 17', 17".

[0063] The mounting element 18, 18', 18" and / or the mounting counter element 19, 19" can have a first group 29 of fixing means receiving recesses 31 and a second group 30 of fixing means receiving recesses 32, different from the first group 29, wherein the fixing means receiving recesses 31, 32 of the two groups 29, 30 differ by their shape and / or type of fixing means receiving recess 31, 32, in particular the diameter and / or the thread type and / or the thread form. For example, the first and / or the second group 29, 30 can be arranged or formed on fixing element receiving recesses 31, 32 along a straight line parallel to the longitudinal axis of the longitudinal body 4, 4' and / or the transverse body 5, 5' and / or the auxiliary longitudinal body 16, 16' and / or the auxiliary transverse body 17, 17', 17". The fixing element receiving recesses 31, 32 of the respective groups 29, 30 can each be spaced at a grid spacing or...The holes may be arranged or formed with a uniform grid spacing. The grid spacing of the fixative receiving recesses 31, 32 of the two groups 29, 30 can be identical, i.e., the distance between a first fixative receiving recess 31 and the adjacent fixative receiving recess 31 of the same group 29 can be identical to the distance between the fixative receiving recesses 32 of the second group 30. This ensures that the fixative receiving recesses 31, 32 form straight, vertically extending groups 33 across the groups.

[0064] The difference in the fixing element receiving recesses 31, 32 of the two groups 29, 30 in the exemplary embodiment is that the inner, first group 29 is designed as threaded bores on fixing element receiving recesses 31; these fixing element receiving recesses 31 may be provided with internal threads. The fixing element receiving recesses 32 of the second group 30 may be designed as dowel pin bores and may have undergone a honing process accordingly.

[0065] The fixing element receiving recesses 31, 32 can be designed to receive dowel pins and / or screws, whereby the insertion and tightening of the fasteners can be carried out by manual screwdrivers and / or by robot-assisted and / or controlled screwdriving tools. Alternatively or additionally, at least section by section, the connection of the longitudinal bodies 4, 4' and / or transverse bodies 5, 5' and / or longitudinal end bodies 7, 7' and / or transverse end bodies 8, 8', 8" and / or transverse element 12, 12', 12" and / or auxiliary longitudinal body 16, 16' and / or auxiliary transverse body 17, 17', 17" can be fixed and / or released by means of locking bolts provided with a handle or an engagement area.Finally, alternatively or additionally, a clamping mechanism (not shown) is also possible, which clamps the longitudinal bodies 4, 4' and / or transverse bodies 5, 5' and / or longitudinal end bodies 7, 7' and / or transverse end bodies 8, 8', 8" and / or transverse element 12, 12', 12" and / or auxiliary longitudinal body 16, 16' and / or auxiliary transverse body 17, 17', 17" to be detachably connected, for example this is done using an eccentric.

[0066] A component holder and / or a component lifter and / or a connecting element 34 can be attached, at least partially, to the longitudinal mounting element 18, 18', 18" and / or the transverse mounting element 19, 19', 19" on the body side. A component lifter can be designed as a lifting tool that makes it possible to lift at least one component, in particular a vehicle component group 2, 2', in order to enable its defined placement and / or mounting on the device 1. A connecting element 34 can serve to connect the device 1 to a mobile transport vehicle, e.g., an automated guided vehicle (AGV), which supports the device 1 at least temporarily. The connection of the device 1 to the installation surface 14 or a factory floor is schematically represented by a block 35, which represents a support element or an AGV for bracing the device 1 against the installation surface 14.

[0067] In general, the interface used for fastening the longitudinal bodies 4, 4' and / or transverse bodies 5, 5' and / or longitudinal end bodies 7, 7' and / or transverse end bodies 8, 8', 8" and / or transverse element 12, 12', 12" and / or auxiliary longitudinal body 16, 16' and / or auxiliary transverse body 17, 17', 17" can be used for at least temporarily fastening further elements that are helpful for the assembly or handling of the device 1.

[0068] In Fig.Figure 4 depicts an assembly step, in which the vehicle component groups 2, 2' are attached to or supported on the base carrier 6 via the auxiliary bodies 13, 13', 13" and, in this state, a vehicle body shell 3, here a car body, is brought into contact with the vehicle component groups 2, 2' and with the device 1 in order to connect them. If the device 1 is used for assembling and / or assembling different vehicles and thus potentially different vehicle component groups 2, 2' and / or vehicle body shells 3, a transverse body 5, 5' can be detachably attached to the at least one longitudinal body 4, 4' in a first position and / or orientation for a first assembly situation and in a second position and / or orientation for a second assembly situation, depending on the specific assembly situation.Vehicle component groups 2, 2' can include, for example, the engine, transmission, front axle, rear axle and / or radiator.
